3607. Klages, K.H. and R.H. Stark. 1949. Grass and grass seed production.. ID Agr. Expt. Sta. Bull. #273.
Lists hay and seed yields of special grasses; discusses stand configuration; N fertilization; adaptation of different grasses.

4077. Mason, J.L. and J.E. Miltimore. 1959. Increase in yield and protein content of native bluebunch wheatgrass from nitrogen fertilization.. Canadian J. Plant Sci. 39:501-504.
Native bluebunch wheatgrass in Okanagan Valley (11" precip.) showed marked response to nitrogen fertilization. Dry matter production doubled with 60N added as ammonium nitrate, protein increased from 3.9 to 6.2 %. Fertilizer also increased ground cover by the desirable grasses.

6813. Thola, J.. 1958. Memo.. USDA - SCS, Pomeroy, WA.
Land taken out of brome grass in rotation soil tested up to 324 lb/ac available N; also shows more moisture with less tillage, better soil structure.

9772. Vigil, M.F. and D.E. Kissel. 1988. Evaluation of urea nitric phosphate for cool season grasses.. Kansas Fertilizer Research, p. 30-31..
Previous studies have compared urea and ammonium nitrate for forage production of cool-season grasses. Results from these studies have generally been similar, although sometimes production has been less with urea in the first year or two of the study. Lower forage production from urea treatment than from ammonium nitrate (AN) is usually attributed to ammonia loss from urea or perhaps increased immobilization of urea. The new urea-nitric phosphate (UNP) fertilizer offers the potential to reduce NH3 loss and or immobilization, therby resulting in improved forage production.
